The 10R-1257 HEUI fuel injector is purpose-engineered for 3126, 3126B and 3126E diesel engines, delivering the precise hydraulic electronic unit injection required for stable combustion across heavy-duty operating cycles. Built as a direct replacement for OEM part 10R-1257 and cross numbers 178-6342, 177-4762, 229-5928 and 177-4752, it ensures correct fitment and reliable integration with the engine control and HEUI hydraulic circuit.
Each remanufactured unit undergoes ultrasonic cleaning, flow testing and calibrated fuel delivery validation to restore balanced cylinder performance, stable idle and reduced exhaust smoke. This HEUI injector is widely specified for motor graders (120H, 135H), track-type tractors and dozens (D5N, D6N), pipelayers (561N), wheel loaders (938G, 938G II), track loaders (953C, 963C) and excavators (325C) used in construction, mining, agricultural machinery maintenance and truck engine rebuilding operations.
For dependable service life, operators should use clean diesel fuel, replace the 1R-0762 fuel filter and 1R-1807 oil filter on schedule, and inspect the 153-8920 wiring harness along with the 214-7568 STOR O-ring seal before installation. When cylinder balance degrades, injectors should be replaced as a matched set, and any fault codes diagnosed with professional diesel scan tools to confirm proper actuation and fuel delivery on 3126 series engines.
